At a water treatment works in Tongxiang, China, 200,000 Aubrick bricks have been used across the site: in the wall panels of every treatment building, the paving between them, and the boundary wall along the road.
Aubrick is our carbon negative earth brick, made by our partner earth4Earth from excavated soil that would otherwise go to landfill, set with a lime binder and compressed rather than fired. Here it fills the panels of each building's concrete frame, from ground level to the roof.
The lime in each brick absorbs carbon dioxide from the air, up to 178g per brick, and holds what it takes in. Across 200,000 bricks, that is up to 35.6 tonnes of CO₂.
The same brick is laid as paving between the buildings, edged with bricks set on end, and as a perforated boundary wall with solid piers.
It is the same brick we supply in the UK as Aubrick, UKCA and CE marked, with a published EPD. At the end of its life it can be crushed and used in new bricks, or returned to the ground as soil.
